This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. babel exports parseSync function
  2. parseSync parses JavaScript source code into a File AST node with Program body and default sourceType module
  3. parseSync accepts parserOpts plugins such as jsx to parse extended syntax without transformation plugins
  4. parseSync populates tokens array when parserOpts.tokens is true
  5. parseSync with sourceType unambiguous parses export statements as module and plain statements as script
  6. parseSync returns null when filename matches ignore pattern in options
  7. parseSync throws a SyntaxError with BABEL_PARSE_ERROR code on invalid syntax
